Hey
@DaHomie!
If you are planing LST, you can start from now on. Just be careful to use width wires to avoid damages on the stems.
I recommend fimming or topping in this type of techniques since it will help controlling the height of the plant.
Just be gentle and don't worry if you accidentally break any stem. Just let it be if its not totally broken or use adhesive tape if you think she will not be able to recover by itself.
Have fun with that trainning!
